Climate change

Can the weather change during the same day?

• YES

• NO

Will the weather tomorrow definitely be the

same as it is today?

• YES

• NO. Weather changes quickly

How would we know if the weather has

changed?

• Look outside the window, check the

  temperature, etc.

• Check the weacther broadcast

• It is impossible to know

If we have one cold summer, does that

mean that our climate has changed?

• Not necessarily. Climate takes decades to

  measure, so one season is not enough

  data to make this claim.

• YES

Can the climate change each day?

• YES

• No. Weather can change daily, but

  climate takes decades or more to

  measure.

How could we measure if the climate was

changing?

• Look at the average weather

  measurements for the past few decades,

  such as temperature and precipitation,

  and look for trends that show that things

  have changed.

• With a thermometer

How would we know if the climate has

changed?

• Places where it was cold might get

  warmer each year; places where it was

  rainy/ snowy might get drier each year;

  there might be more extreme weather in

  some areas, etc.

• We cannot know
